One of the worst movies I've seen

But that probably has to do with me - I don't like loud stuff or overly glittery people. The opening had me thinking I was going to like it, as I'm very curious what goes on after these school shootings.
But I didn't get the attraction to her song, nor her. Nor any of the characters.
And she's religious, but then she acts so like she's not?
Maybe it's just showing how big stars get so lost?
Glad it was free from public library, but can't recommend it at all. I'd give it one star, just because the filming was decent.
